+# QMK Breaking Change - 2019 Aug 30
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+This document marks the inaugural Breaking Change merge. A list of changes follows.
+
+## Core code formatting with clang-format
+
+* All core files (`drivers/`, `quantum/`, `tests/`, and `tmk_core/`) have been formatted with clang-format
+* A travis process to reformat PR's on merge has been instituted
+* You can use the new CLI command `qmk cformat` to format before submitting your PR if you wish.
+
+## LUFA USB descriptor cleanup
+
+* Some code cleanups related to the USB HID descriptors on AVR keyboards, to make them easier to read and understand
+* More information: see https://github.com/qmk/qmk_firmware/pull/4871
+* No behaviour changes anticipated and no keymaps modified
+
+## Migrating `ACTION_LAYER_MOMENTARY()` entries in `fn_actions` to `MO()` keycodes
+
+* `fn_actions` is deprecated, and its functionality has been superseded by direct keycodes and `process_record_user()`
+* The end result of removing this obsolete feature should result in a decent reduction in firmware size and code complexity
+* All keymaps affected are recommended to switch away from `fn_actions` in favour of the [custom keycode](https://docs.qmk.fm/#/custom_quantum_functions) and [macro](https://docs.qmk.fm/#/feature_macros) features
+
+## Update Atreus to current code conventions
+
+* Duplicate include guards have bypassed the expected header processing behavior
+* All keymaps affected are recommended to remove duplication of `<keyboard>/config.h` to `<keyboard>/keymaps/<user>/config.h` and only provide overrides at the keymap level
+
+## Backport changes to keymap language files from ZSA fork
+
+* Fixes an issue in the `keymap_br_abnt2.h` file that includes the wrong source (`keymap_common.h` instead of `keymap.h`)
+* Updates the `keymap_swedish.h` file to be specific to swedish, and not just "nordic" in general. 
+* Any keymaps using this will need to remove `NO_*` and replace it with `SE_*`. 
+
+## Update repo to use LUFA as a git submodule
+
+* `/lib/LUFA` removed from the repo
+* LUFA set as a submodule, pointing to qmk/lufa
+* This should allow more flexibility with LUFA, and allow us to keep the sub-module up to date, a lot more easily.  It was ~2 years out of date with no easy path to fix that.  This prevents that from being an issue in the future
+  
+## Migrating `ACTION_BACKLIGHT_*()` entries in `fn_actions` to `BL_` keycodes
+
+* `fn_actions` is deprecated, and its functionality has been superseded by direct keycodes and `process_record_user()`
+* All keymaps using these actions have had the relevant `KC_FN*` keys replaced with the equivalent `BL_*` keys
+* If you currently use `KC_FN*` you will need to replace `fn_actions` with the [custom keycode](https://docs.qmk.fm/#/custom_quantum_functions) and [macro](https://docs.qmk.fm/#/feature_macros) features
+
+## Remove `KC_DELT` alias in favor of `KC_DEL`
+
+* `KC_DELT` was a redundant, undocumented alias for `KC_DELETE`
+* It has been removed and all its uses replaced with the more common `KC_DEL` alias
+* Around 90 keymaps (mostly for ErgoDox boards) have been modified as a result

+# QMK Breaking Change - 2020 Feb 29 Changelog
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+
+## Update ChibiOS/ChibiOS-Contrib/uGFX submodules
+
+* General Notes
+    * A `make git-submodule` may be required after pulling the latest QMK firmware code to update affected submodules to the upgraded revisions
+    * Enabling link-time-optimization (`LINK_TIME_OPTIMIZATION_ENABLE = yes`) should work on a lot more boards
+* Upgrade to ChibiOS ver19.1.3
+    * This will allow QMK to update to upstream ChibiOS a lot easier -- the old version was ~2 years out of date. Automated update scripts have been made available to simplify future upgrades.
+    * Includes improved MCU support and bugfixes
+    * ChibiOS revision is now included in Command output
+    * Timers should now be more accurate
+* Upgrade to newer ChibiOS-Contrib
+    * Also includes improved MCU support and bugfixes
+    * ChibiOS-Contrib revision is now included in Command output
+* Upgrade to newer uGFX
+    * Required in order to support updated ChibiOS
+
+
+## Fix ChibiOS timer overflow for 16-bit SysTick devices
+
+* On 16-bit SysTick devices, the timer subsystem in QMK was incorrectly dealing with overflow.
+    * When running at a 100000 SysTick frequency (possible on 16-bit devices, but uncommon), this overflow would occur after 0.65 seconds.
+* Timers are now correctly handling this overflow case and timing should now be correct on ChibiOS/ARM.
+
+
+## Update LUFA submodule
+
+* Updates the LUFA submodule to include updates from upstream (abcminiuser/lufa)
+* Includes some cleanup for QMK DFU generation
+
+
+## Encoder flip
+
+* Flips the encoder direction so that `clockwise == true` is for actually turning the knob clockwise
+* Adds `ENCODER_DIRECTION_FLIP` define, so that reversing the expected dirction is simple for users.
+* Cleans up documentation page for encoders
+
+
+## Adding support for `BACKLIGHT_ON_STATE` for hardware PWM backlight
+
+* Previously, the define only affected software PWM, and hardware PWM always assumed an N-channel MOSFET.
+* The hardware PWM backlight setup has been updated to respect this option.
+* The default "on" state has been changed to `1` - **this impacts all keyboards using software PWM backlight that do not define it explicitly**. If your keyboard's backlight is acting strange, it may have a P-channel MOSFET, and will need to have `#define BACKLIGHT_ON_STATE 0` added to the keyboard-level `config.h`. Please see the PR for more detailed information.
+
+
+## Migrating `ACTION_LAYER_TAP_KEY()` entries in `fn_actions` to `LT()` keycodes
+
+* `fn_actions` is deprecated, and its functionality has been superseded by direct keycodes and `process_record_user()`
+* The end result of removing this obsolete feature should result in a decent reduction in firmware size and code complexity
+* All keymaps affected are recommended to switch away from `fn_actions` in favour of the [custom keycode](https://docs.qmk.fm/#/custom_quantum_functions) and [macro](https://docs.qmk.fm/#/feature_macros) features
+
+
+## Moving backlight keycode handling to `process_keycode/`
+
+* This refactors the backlight keycode logic to be clearer and more modular.
+* All backlight-related keycodes are now actioned in a single file.
+* The `ACTION_BACKLIGHT_*` macros have also been deleted. If you are still using these in a `fn_actions[]` block, please switch to using the backlight keycodes or functions directly.
+
+
+## Refactor Planck keymaps to use Layout Macros
+
+* Refactor Planck keymaps to use layout macros instead of raw matrix assignments
+* Makes keymaps revision-agnostic
+* Should reduce noise and errors in Travis CI logs
+
+
+## GON NerD codebase refactor
+
+* Splits the codebase for GON NerD 60 and NerdD TKL PCBs into two separate directories.
+* If your keymap is for a NerD 60 PCB, your `make` command is now `make gon/nerd60:<keymap>`.
+* If your keymap is for a NerD TKL PCB, your `make` command is now `make gon/nerdtkl:<keymap>`.

+# QMK Breaking Change - 2020 May 30 Changelog
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+The list of changes follows.
+
+
+## Core Changes
+
+### Converting V-USB usbdrv to a submodule
+
+[#8321](https://github.com/qmk/qmk_firmware/pull/8321) and [qmk_compiler#62](https://github.com/qmk/qmk_compiler/pull/62).
+
+These PRs move the V-USB driver code out of the qmk_firmware repository and into a submodule pointed at https://github.com/obdev/v-usb. This will make it easier to update the codebase if needed, while applying any potential QMK-specific modifications by forking it to the QMK GitHub organization.
+
+### Unify Tap Hold functions and documentation
+
+[#8348](https://github.com/qmk/qmk_firmware/pull/8348)
+
+Updates all of the per key tap-hold functions to pass the `keyrecord_t` structure, and include documentation changes.
+
+Any remaining versions or code outside of the main repo will need to be converted: 
+| Old function                                         | New Function                                                              |
+|------------------------------------------------------|---------------------------------------------------------------------------|
+|`uint16_t get_tapping_term(uint16_t keycode)`         |`uint16_t get_tapping_term(uint16_t keycode, keyrecord_t *record)`         |
+|`bool get_ignore_mod_tap_interrupt(uint16_t keycode)` |`bool get_ignore_mod_tap_interrupt(uint16_t keycode, keyrecord_t *record)` |
+
+### Python Required In The Build Process
+
+[#9000](https://github.com/qmk/qmk_firmware/pull/9000)
+
+This is the last release of QMK that will work without having Python 3.6 (or later) installed. If your environment is not fully setup you will get a warning instructing you to set it up.
+
+After the next breaking change you will not be able to build if `bin/qmk hello` does not work.
+
+### Upgrade from tinyprintf to mpaland/printf
+
+[#8269](https://github.com/qmk/qmk_firmware/pull/8269)
+
+- Provides debug functionality on ChibiOS/ARM that is more compliant than previous integrations.
+- Less maintenence, fewer QMK customisations, and allows QMK to sidestep previous compile and runtime issues.
+- A `make git-submodule` may be required after pulling the latest QMK Firmware code to update to the new dependency.
+
+### Fixed RGB_DISABLE_AFTER_TIMEOUT to be seconds based & small internals cleanup
+
+[#6480](https://github.com/qmk/qmk_firmware/pull/6480)
+
+- Changes `RGB_DISABLE_AFTER_TIMEOUT` to be based on milliseconds instead of ticks.
+- Includes a code cleanup, resulting in a savings of 100 bytes, depending on features used.
+- Fixed issues with timeouts / suspending at the wrong time not turning off all LEDs in some cases.
+
+The `RGB_DISABLE_AFTER_TIMEOUT` definition is now deprecated, and has been superseded by `RGB_DISABLE_TIMEOUT`. To use the new definition, rename `RGB_DISABLE_AFTER_TIMEOUT` to `RGB_DISABLE_TIMEOUT` in your `config.h` file, and multiply the value set by 1200.
+
+Before: `#define RGB_DISABLE_AFTER_TIMEOUT 100`  
+After: `#define RGB_DISABLE_TIMEOUT 120000`
+
+### Switch to qmk forks for everything
+
+[#9019](https://github.com/qmk/qmk_firmware/pull/9019)
+
+Fork all QMK submodules to protect against upstream repositories disappearing.
+
+### code cleanup regarding deprecated macro PLAY_NOTE_ARRAY by replacing it with PLAY_SONG
+
+[#8484](https://github.com/qmk/qmk_firmware/pull/8484)
+
+Removes the deprecated `PLAY_NOTE_ARRAY` macro. References to it are replaced with `PLAY_SONG`, which references the same function.
+
+### fixing wrong configuration of AUDIO feature
+
+[#8903](https://github.com/qmk/qmk_firmware/pull/8903) and [#8974](https://github.com/qmk/qmk_firmware/pull/8974)
+
+`audio_avr.c` does not default to any pin; there has to be a #define XX_AUDIO in config.h at some level for Audio to actually work. Otherwise, the Audio code ends up cluttering the firmware, possibly breaking builds because the maximum allowed firmware size is exceeded.
+
+These changes fix this by disabling Audio on keyboards that have the feature misconfigured, and therefore non-functional.
+
+Also, add a compile-time error to alert the user to a missing pin-configuration (on AVR boards) when `AUDIO_ENABLE = yes` is set.
+
+
+## Keyboard Refactors
+
+### Migrating Lily58 to use split_common
+
+[#6260](https://github.com/qmk/qmk_firmware/pull/6260)
+
+Modifies the default firmware for Lily58 to use the `split_common` library, instead of including and depending on its own set of libraries for the following functionality:
+
+- SSD1306 display
+- i2c for OLED
+- Serial Communication
+
+This allows current lily58 firmware to advance with updates to the `split_common` library, which is shared with many other split keyboards.
+
+#### To migrate existing Lily58 firmware:
+
+[Changes to `config.h`](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-445ac369c8717dcd6fc6fc3630836fc1):
+- Remove `#define SSD1306OLED` from config.h
+
+
+[Changes to `keymap.c`](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7):
+- Find/Replace each instance of `#ifdef SSD1306OLED` with `#ifdef OLED_DRIVER_ENABLE`
+- The following changes are for compatibility with the OLED driver. If you don't use the OLED driver you may safely delete [this section](https://github.com/qmk/qmk_firmware/blob/e6b9980bd45c186f7360df68c24b6e05a80c10dc/keyboards/lily58/keymaps/default/keymap.c#L144-L190)
+- Alternatively, if you did not change the OLED code from that in `default`, you may find it easier to simply copy the [relevant section](https://github.com/qmk/qmk_firmware/blob/4ac310668501ae6786c711ecc8f01f62ddaa1c0b/keyboards/lily58/keymaps/default/keymap.c#L138-L172). Otherwise, the changes you need to make are as follows (sample change [here](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7R138-R173))
+- [Remove](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7L138-L141) the block
+```c
+#ifdef SSD1306OLED      
+  iota_gfx_init(!has_usb());   // turns on the display  
+#endif
+```
+- Within the block bounded by `#ifdef OLED_DRIVER_ENABLE` and `#endif // OLED_DRIVER_ENABLE`, add the following block to ensure that your two OLEDs are rotated correctly across the left and right sides:
+```c
+oled_rotation_t oled_init_user(oled_rotation_t rotation) {
+  if (!is_keyboard_master())
+    return OLED_ROTATION_180;  // flips the display 180 degrees if offhand
+  return rotation;
+}
+```
+- Remove the functions `matrix_scan_user`, `matrix_update` and `iota_gfx_task_user`
+- Find/Replace `matrix_render_user(struct CharacterMatrix *matrix)` with `iota_gfx_task_user(void)`
+- Find/Replace `is_master` with `is_keyboard_master()`
+- For each instance of `matrix_write_ln(matrix, display_fn())`, rewrite it as `oled_write_ln(read_layer_state(), false);`
+- For each instance of `matrix_write(matrix, read_logo());`, replace with `oled_write(read_logo(), false);`
+
+### Refactor zinc to use split_common
+
+[#7114](https://github.com/qmk/qmk_firmware/pull/7114) and [#9171](https://github.com/qmk/qmk_firmware/pull/9171)
+
+* Refactor to use split_common and remove split codes under the zinc/revx/
+* Add - backlight RGB LED and/or underglow RGB LED option
+* Add - continuous RGB animations feature (between L and R halves) 
+* Fix - keymap files to adapt to changes
+    * all authors of keymaps confirmed this PR
+* Update - documents and rules.mk
+
+### Refactor of TKC1800 to use common OLED code
+
+[#8472](https://github.com/qmk/qmk_firmware/pull/8472)
+
+Modifies the default firmware for TKC1800 to use the in-built I2C and OLED drivers, instead of including and depending on its own set of libraries for the following functionality:
+
+- SSD1306 display
+- i2c for OLED
+
+This allows current TKC1800 firmware to advance with updates to those drivers, which are shared with other keyboards.
+
+#### To migrate existing TKC1800 firmware:
+
+[Changes to `config.h`](https://github.com/qmk/qmk_firmware/pull/8472/files#diff-d10b26e676b4a55cbb00d71955116526):
+- Remove `#define SSD1306OLED` from config.h
+
+[Changes to `tkc1800.c`](https://github.com/qmk/qmk_firmware/pull/8472/files#diff-3b35bd30abe89c8110717c6972cd2cc5):
+- Add the following to avoid debug errors on HID_listen if the screen is not present
+```c
+void keyboard_pre_init_kb(void) {
+  setPinInputHigh(D0);
+  setPinInputHigh(D1);
+
+  keyboard_pre_init_user();
+}
+```
+
+[Changes to `keymap.c`](https://github.com/qmk/qmk_firmware/pull/8472/files#diff-05a2a344ce27e4d045fe68520ccd4771):
+- Find/Replace each instance of `#ifdef SSD1306OLED` with `#ifdef OLED_DRIVER_ENABLE`
+- The following changes are for compatibility with the OLED driver. If you don't use the OLED driver you may safely delete [this section](https://github.com/qmk/qmk_firmware/blob/e6b9980bd45c186f7360df68c24b6e05a80c10dc/keyboards/lily58/keymaps/default/keymap.c#L144-L190)
+- [Remove](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7L91-L158) the block
+```c
+#ifdef SSD1306OLED      
+  iota_gfx_init(!has_usb());   // turns on the display  
+#endif
+```
+- Within the block bounded by `#ifdef OLED_DRIVER_ENABLE` and `#endif // OLED_DRIVER_ENABLE`, add the following block to ensure that your two OLEDs are rotated correctly across the left and right sides:
+```c
+oled_rotation_t oled_init_user(oled_rotation_t rotation) {
+  if (!is_keyboard_master())
+    return OLED_ROTATION_180;  // flips the display 180 degrees if offhand
+  return rotation;
+}
+```
+- Remove the function `iota_gfx_task_user`
+
+### Split HHKB to ANSI and JP layouts and Add VIA support for each
+
+[#8582](https://github.com/qmk/qmk_firmware/pull/8582)
+
+- Splits the HHKB codebase into two separate folders `keyboards/hhkb/ansi` and `keyboards/hhkb/jp`.
+- Adds VIA Configurator support for both versions.
+
+#### Migrating existing HHKB keymaps
+
+- Remove any checks for the `HHKB_JP` definition
+  - All checks for this definition have been removed, and each version uses the source that is appropriate to that version.
+- Move the directory for your keymap into the appropriate `keymaps` directory
+  - `keyboards/hhkb/ansi/keymaps/` for ANSI HHKBs
+  - `keyboards/hhkb/jp/keymaps/` for HHKB JPs
+- Compile with the new keyboard names
+  - This PR changes the compilation instructions for the HHKB Alternate Controller. To compile firmware for this controller moving forward, use:
+    - `make hhkb/ansi` for ANSI-layout HHKBs
+    - `make hhkb/jp` for HHKB JP keyboards
+

+### Updated Keyboard Codebases :id=keyboard-updates
+
+#### Keebio RGB wiring update ([#7754](https://github.com/qmk/qmk_firmware/pull/7754))
+
+This pull request changes the configuration for Keebio split boards to use the same RGB strip wiring for each half, which provides the following improvements:
+
+* Easier wiring due to one fewer wire needed (the wire between left DOut to extra data pin) and the fact that wiring is the same for both halves.
+* RGB LEDs can be controlled by each half now instead of just master half.
+* Extra data line is freed up to allow for I2C usage instead of serial.
+
+If you have customized the value of `RGBLED_SPLIT` for your keymap, you will need to undefine it using `#undef RGBLED_SPLIT` before defining it to your customized value.
+
+This change affects:
+
+* BFO-9000
+* Fourier
+* Iris rev2
+* Levinson, revs. 1 and 2
+* Nyquist, revs. 1 and 2
+* Quefrency rev1
+* Viterbi, revs. 1 and 2
+
+### Changes to Core Functionality :id=core-updates
+
+* Bigger Combo index ([#9318](https://github.com/qmk/qmk_firmware/pull/9318))
+
+Allows the Combo feature to support more than 256 combos.
+
+Any fork that uses `process_combo_event` needs to update the function's first argument to `uint16_t`:
+
+* Old function: `void process_combo_event(uint8_t combo_index, bool pressed)`
+* New function: `void process_combo_event(uint16_t combo_index, bool pressed)`
+
+
+## Core Changes :id=core-changes
+
+### Fixes :id=core-fixes
+
+* Mousekeys: scrolling acceleration is no longer coupled to mouse movement acceleration ([#9174](https://github.com/qmk/qmk_firmware/pull/9174))
+* Keymap Extras: correctly assign Question Mark in Czech layout ([#9987](https://github.com/qmk/qmk_firmware/pull/9987))
+
+### Additions and Enhancements :id=core-additions
+
+* allow for WS2812 PWM to work on DMAMUX-capable devices ([#9471](https://github.com/qmk/qmk_firmware/pull/9471))
+  * Newer STM32 MCUs have a DMAMUX peripheral, which allows mapping of DMAs to different DMA streams, rather than hard-defining the target streams in silicon.
+  * Affects STM32L4+ devices, as well as the soon-to-be-supported-by-QMK STM32G4/H7 families.
+  * Tested on F303/Proton C (ChibiOS v19, non-DMAMUX), G474 (ChibiOS v20, with DMAMUX).
+* dual-bank STM32 bootloader support ([#8778](https://github.com/qmk/qmk_firmware/pull/8778) and [#9738](https://github.com/qmk/qmk_firmware/pull/9738))
+  * Adds support for STM32 dual-bank flash bootloaders, by toggling a GPIO during early init in order to charge an RC circuit attached to `BOOT0`.
+  * The main rationale behind this is that dual-bank STM32 devices unconditionally execute user-mode code, regardless of whether or not the user-mode code jumps to the bootloader. If either flash bank is valid (and `BOOT0` is low), then the built-in bootloader will skip any sort of DFU.
+  * This PR allows for the initialisation sequencing to charge the RC circuit based on the example circuit posted on Discord, effectively pulling `BOOT0` high before issuing the system reset. As the RC circuit takes a while to discharge, the system reset executes the ROM bootloader which subsequently sees `BOOT0` high, and starts executing the DFU routines.
+  * Tested with STM32L082 (with current QMK+current ChibiOS), and STM32G474 (against ChibiOS 20.x).
+* update Space Cadet and Tap Dance features to use Custom Tapping Term when appropriate ([#6259](https://github.com/qmk/qmk_firmware/pull/6259))
+  * For the Tap Dance feature, this completely removes the need for the `ACTION_TAP_DANCE_FN_ADVANCED_TIME` dance.
+* HID Joystick Interface ([#4226](https://github.com/qmk/qmk_firmware/pull/4226) and [#9949](https://github.com/qmk/qmk_firmware/pull/9949 "Fix Joystick Compile Issues"))
+  * This implements a joystick feature, including a joystick_task function called from TMK, specific keycodes for joystick buttons and a USB HID interface.
+  * Tested on V-USB backend and Proton C; compiles but untested on LUFA.
+  * In order to test, you have to add `JOYSTICK_ENABLE = yes` to your `rules.mk` and
+    ```c
+    #define JOYSTICK_BUTTON_COUNT 8
+    #define JOYSTICK_AXES_COUNT 2
+    ```
+    in your config.h.
+* Christmas RGB Underglow animation now fades between green and red ([#7648](https://github.com/qmk/qmk_firmware/pull/7648))
+  * `RGBLIGHT_EFFECT_CHRISTMAS_INTERVAL` has been greatly decreased; please check your animation if you have customized this value.
+* layer state now initializes on startup ([#8318](https://github.com/qmk/qmk_firmware/pull/8318))
+  * This should produce more consistent behavior between the two functions and layer masks.
+* added support for HSV->RGB conversion without using CIE curve ([#9856](https://github.com/qmk/qmk_firmware/pull/9856))
+* added NOEEPROM functions for RGB Matrix ([#9487](https://github.com/qmk/qmk_firmware/pull/9487))
+  * Added eeprom_helpers for toggle, mode, sethsv, speed, similar to rgblight versions.
+  * Added set_speed function.
+  * Added helper functions, similar to those in rgblight, in order to add NOEEPROM versions of toggle, step, hue, sat, val, and speed.
+  * Minor: spelling correction for EEPROM in a debug message.
+* flashing firmware using `st-flash` utility from [STLink Tools](https://github.com/stlink-org/stlink) is now supported ([#9964](https://github.com/qmk/qmk_firmware/pull/9964))
+* add ability to dump all makefile variables for the specified target ([#8256](https://github.com/qmk/qmk_firmware/pull/8256))
+  * Adds a new subtarget to builds, `dump_vars`, which allows for printing out all the variables that make knows about, after all substitutions occur.
+  * Example: `make handwired/onekey/proton_c:default:dump_vars`
+* add ability to change the Auto Shift timeout in real time ([#8441](https://github.com/qmk/qmk_firmware/pull/8441))
+* added a timer implementation for backlight on ChibiOS ([#8291](https://github.com/qmk/qmk_firmware/pull/8291))
+* added a third endpoint to V-USB keyboards ([#9020](https://github.com/qmk/qmk_firmware/pull/9020))
+* added a method to read the OLED display buffer from user space ([#8777](https://github.com/qmk/qmk_firmware/pull/8777))
+* K-Type refactor ([#9864](https://github.com/qmk/qmk_firmware/pull/9864))
+  * The K-Type has been refactored to use QMK's native matrix scanning routine, and now has partial support for the RGB Matrix feature.
+* Joysticks can now be used without defining analog pins ([#10169](https://github.com/qmk/qmk_firmware/pull/10169))
+
+### Clean-ups and Optimizations :id=core-optimizations
+
+* iWRAP protocol removed ([#9284](https://github.com/qmk/qmk_firmware/pull/9284))
+* work begun for consolidation of ChibiOS platform files ([#8327](https://github.com/qmk/qmk_firmware/pull/8327) and [#9315](https://github.com/qmk/qmk_firmware/pull/9315))
+  * Start of the consolidation work to move the ChibiOS board definitions as well as the default set of configuration files for existing board definitions used by keyboards.
+    * Uses `/platforms/chibios` as previously discussed on discord.
+    * Consolidates the Proton C configs into the generic F303 definitions.
+    * Allows for defining a default set of `chconf.h`, `halconf.h`, and `mcuconf.h` files within the platform definition, which is able to be overridden by the keyboard directly, though include path ordering.
+    * Adds template `chconf.h`, `halconf.h`, `mcuconf.h`, and `board.h` that can be dropped into a keyboard directory, in order to override rather than replace the entire contents of the respective files.
+    * Removed Proton C QMK board definitions, falling back to ChibiOS board definitions with QMK overrides.
+* Various tidy-ups for USB descriptor code ([#9005](https://github.com/qmk/qmk_firmware/pull/9005))
+  * Renamed `keyboard_led_stats` in lufa.c and ChibiOS usb_main.c to `keyboard_led_state`, as well as `vusb_keyboard_leds`, for consistency
+  * Formatted CDC and MIDI descriptors better
+  * Removed `ENDPOINT_CONFIG` macro, it seems pointless and removes the need for endpoint address defines in the middle of the endpoint numbering enum
+  * Fixed (possibly?) V-USB `GET_REPORT` request handling. Not sure about this one, but the existing code appears to always return an empty report - now `send_keyboard` sets this variable to the current report, matching what the LUFA code does.
+* converted `CONSUMER2BLUEFRUIT()` and `CONSUMER2RN42()` macros to static inline functions ([#9055](https://github.com/qmk/qmk_firmware/pull/9055))
+* Additional cleanups for V-USB code ([#9310](https://github.com/qmk/qmk_firmware/pull/9310))
+  * Removing the UART stuff entirely, now that we have Console support. Also fixing up various other things; switching some `debug()` calls to `dprintf()`, moved `raw_hid_report` out of the way so that we can implement the shared endpoint stuff.
+* removed inclusion of `adafruit_ble.h` from `ssd1306.c` ([#9355](https://github.com/qmk/qmk_firmware/pull/9355))
+* `outputselect.c` is no longer compiled if Bluetooth is disabled ([#9356](https://github.com/qmk/qmk_firmware/pull/9356))
+* `analogRead()` deprecated in favor of `analogReadPin()` ([#9023](https://github.com/qmk/qmk_firmware/pull/9023))
+* forcibly disable NKRO on V-USB controllers ([#9054](https://github.com/qmk/qmk_firmware/pull/9054))
+* removed warning if running backlight on STM32F072 ([#10040](https://github.com/qmk/qmk_firmware/pull/10040))
+* removed unused CORTEX_VTOR_INIT rules.mk option ([#10053](https://github.com/qmk/qmk_firmware/pull/10053))
+* improved handling for enabling Link Time Optimization ([#9832](https://github.com/qmk/qmk_firmware/pull/9832))
+* streamline rules for supporting Kiibohd bootloader ([#10129](https://github.com/qmk/qmk_firmware/pull/10129))
+* Define `STM32_DMA_REQUIRED` when using DMA-based WS2812 driver on STM32 ([#10127](https://github.com/qmk/qmk_firmware/pull/10127))
+* fix DMA stream ID calculation in ws2812_pwm ([#10008](https://github.com/qmk/qmk_firmware/pull/10008))
+* remove support for Adafruit EZ Key Bluetooth controller ([#10103](https://github.com/qmk/qmk_firmware/pull/10103))
+
+
+## QMK Infrastructure and Internals :id=qmk-internals
+
+* Attempt to fix CI for non-master branches. ([#9308](https://github.com/qmk/qmk_firmware/pull/9308))
+  * Actually fetch the branch we're attempting to compare against.
+* Run `qmk cformat` on `develop` branch ([#9501](https://github.com/qmk/qmk_firmware/pull/9501))
+* minor refactor of Bluetooth API ([#9905](https://github.com/qmk/qmk_firmware/pull/9905))

+# QMK Breaking Change - 2020 Nov 28 Changelog
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.

+# QMK Breaking Changes - 2021 February 27 Changelog
+
+## Changes Requiring User Action
+
+The following keyboards have had their source moved within QMK:
+
+Old Keyboard Name | New Keyboard Name
+:---------------- | :----------------
+bear_65 | jacky_studio/bear_65
+s7_elephant/rev1 | jacky_studio/s7_elephant/rev1
+s7_elephant/rev2 | jacky_studio/s7_elephant/rev2
+aplx6 | aplyard/aplx6/rev1
+southpaw75 | fr4/southpaw75
+
+The [Aplyard Aplx6 rev2](https://github.com/qmk/qmk_firmware/tree/0.12.0/keyboards/aplyard/aplx6/rev1) and the [FR4Boards Unix60](https://github.com/qmk/qmk_firmware/tree/0.12.0/keyboards/fr4/unix60) have also been added as part of these changes.
+
+Additionally, the `handwired/bluepill/bluepill70` keyboard has been removed.
+
+## Core Changes
+
+### ChibiOS Update and Config Migration
+
+QMK's ChibiOS and ChibiOS-Contrib submodules have been updated to version 20.3.2.
+
+Along with this, QMK now provides default configuration files for all commonly-supported ARM microcontrollers running on ChibiOS. As such, keyboards are now only required to define settings which differ from the defaults, thereby reducing the size of pull requests for keyboards running atop ChibiOS.
+
+### QMK Infrastructure and Internals
+
+Python is now required to build QMK. The minimum Python version has been increased to 3.7.
+
+The power of `info.json` has been massively expanded. Most keyboard parameters can now be expressed in `info.json` instead of `config.h`/`rules.mk`. This should make maintaining keyboards easier, and will enable tooling that can allow non-technical users to add and maintain QMK keyboards without writing any code.
+
+To ease migration a new command has been provided, `qmk generate-info-json -kb <keyboard>`. You can use this command to generate a complete `info.json` file for a keyboard and then remove the duplicate information from `config.h` and `rules.mk`. 
+
+Detailed example showing how to generate a new info.json and identify duplicate keys:
+
+```
+user@hostname:~/qmk_firmware/keyboards/lets_split:0$ qmk generate-info-json > new-info.json
+user@hostname:~/qmk_firmware/keyboards/lets_split:0$ mv new-info.json info.json

+# QMK Breaking Changes - 2021 May 29 Changelog
+
+## Notable Changes :id=notable-changes
+
+### RGB Matrix support for split common ([#11055](https://github.com/qmk/qmk_firmware/pull/11055)) :id=rgb-matrix-split-common
+
+Split boards can now use RGB Matrix without defining a custom matrix.
+
+### Teensy 3.6 support ([#12258](https://github.com/qmk/qmk_firmware/pull/12258)) :id=teensy-3-6-support
+
+Added support for MK66F18 (Teensy 3.6) microcontroller.
+
+### New command: qmk console ([#12828](https://github.com/qmk/qmk_firmware/pull/12828)) :id=new-command-qmk-console
+
+A new `qmk console` command has been added for attaching to your keyboard's console. It operates similiarly to QMK Toolbox by allowing you to connect to one or more keyboard consoles to display debugging messages.
+
+### Improved command: qmk config :id=improve-command-qmk-config
+
+We've updated the `qmk config` command to show only the configuration items you have actually set. You can now display (almost) all of the available configuration options, along with their default values, using `qmk config -a`.
+

+The [Function96 V2](https://github.com/qmk/qmk_firmware/tree/0.13.0/keyboards/function96/v2) has also been added as part of these changes.
+
+The codebase for the [Durgod K320](https://github.com/qmk/qmk_firmware/tree/0.13.0/keyboards/durgod/k320) has been reworked in anticipation of additional Durgod keyboards gaining QMK support.
+
+Additionally, the `crkbd/rev1/legacy` keyboard has been removed.
+
+### Bootmagic Deprecation and Refactor ([#12172](https://github.com/qmk/qmk_firmware/pull/12172)) :id=bootmagic-deprecation-and-refactor
+
+QMK has decided to deprecate the full Bootmagic feature and leave Bootmagic Lite as the only remaining option.
+
+This pull request changes the behavior of `BOOTMAGIC_ENABLE` such that specifying `BOOTMAGIC_ENABLE = yes` enables Bootmagic Lite instead of full Bootmagic.
+
+If attempts to use Bootmagic functionality result in unexpected behavior, check your `rules.mk` file and change the `BOOTMAGIC_ENABLE` setting to specify either `lite` or `full`.
+
+#### Tentative Deprecation Schedule
+
+This is the current planned roadmap for the behavior of `BOOTMAGIC_ENABLE`:
+
+- From 2021 May 29, setting `BOOTMAGIC_ENABLE = yes` will enable Bootmagic Lite instead of full Bootmagic.
+- From 2021 Aug 28, `BOOTMAGIC_ENABLE` must be either `yes`, `lite`, or `no` – setting `BOOTMAGIC_ENABLE = full` will cause compilation to fail.
+- From 2021 Nov 27, `BOOTMAGIC_ENABLE` must be either `yes` or `no` – setting `BOOTMAGIC_ENABLE = lite` will cause compilation to fail.
+
+### Removal of LAYOUT_kc ([#12160](https://github.com/qmk/qmk_firmware/pull/12160)) :id=removal-of-layout-kc
+
+We've removed support for `LAYOUT_kc` macros, if your keymap uses one you will need to update it use a regular `LAYOUT` macro.
+
+### Encoder callbacks are now boolean ([#12805](https://github.com/qmk/qmk_firmware/pull/12805), [#12985](https://github.com/qmk/qmk_firmware/pull/12985)) :id=encoder-callback-boolean
+
+To allow for keyboards to override (or not) keymap level code the `encoder_update_kb` function has been changed from `void` to `bool`. You will need to update your function definition to reflect this and ensure that you return a `true` or `false` value.
+
+Example code before change:
+
+```c
+void encoder_update_kb(uint8_t index, bool clockwise) {
+    encoder_update_user(index, clockwise);
+}
+
+void encoder_update_user(uint8_t index, bool clockwise) {
+    if (index == 0) { /* First encoder */
+        if (clockwise) {
+            tap_code(KC_PGDN);
+        } else {
+            tap_code(KC_PGUP);
+        }
+    } else if (index == 1) { /* Second encoder */
+        if (clockwise) {
+            tap_code(KC_DOWN);
+        } else {
+            tap_code(KC_UP);
+        }
+    }
+}
+```
+
+Example code after change:
+
+```c
+bool encoder_update_kb(uint8_t index, bool clockwise) {
+    return encoder_update_user(index, clockwise);
+}
+
+bool encoder_update_user(uint8_t index, bool clockwise) {
+    if (index == 0) { /* First encoder */
+        if (clockwise) {
+            tap_code(KC_PGDN);
+        } else {
+            tap_code(KC_PGUP);
+        }
+    } else if (index == 1) { /* Second encoder */
+        if (clockwise) {
+            tap_code(KC_DOWN);
+        } else {
+            tap_code(KC_UP);
+        }
+    }
+    return true; 
+    // If you return true, this will allow the keyboard level code to run, as well. 
+    //Returning false will override the keyboard level code. Depending on how the keyboard level function is set up.
+}
+```

+# QMK Breaking Changes - 2021 August 28 Changelog
+
+## Notable Features :id=notable-features
+
+### Combo processing improvements ([#8591](https://github.com/qmk/qmk_firmware/pull/8591)) :id=combo-processing-improvements
+
+Combo processing has been reordered with respect to keypress handling, allowing for much better compatibility with mod taps.
+
+It is also now possible to define combos that have keys overlapping with other combos, triggering only one. For example, a combo of `A`, `B` can coexist with a longer combo of `A`, `B`, `C` -- previous functionality would trigger both combos if all three keys were pressed.
+
+### Key Overrides ([#11422](https://github.com/qmk/qmk_firmware/pull/11422)) :id=key-overrides
+
+QMK now has a new feature: [key overrides](https://docs.qmk.fm/#/feature_key_overrides). This feature allows for overriding the output of key combinations involving modifiers. As an example, pressing <kbd>Shift+2</kbd> normally results in an <kbd>@</kbd> on US-ANSI keyboard layouts -- the new key overrides allow for adding similar functionality, but for any <kbd>modifier + key</kbd> press.
+
+To illustrate, it's now possible to use the key overrides feature to translate <kbd>Shift + Backspace</kbd> into <kbd>Delete</kbd> -- an often-requested example of where this functionality comes in handy.
+
+There's far more to describe that what lives in this changelog, so head over to the [key overrides documentation](https://docs.qmk.fm/#/feature_key_overrides) for more examples and info.
+
+### Digitizer support ([#12851](https://github.com/qmk/qmk_firmware/pull/12851))
+
+QMK gained the ability to pretend to be a digitizer device -- much like a tablet device. A mouse uses delta-coordinates -- move up, move right -- but a digitizer works with absolute coordinates -- top left, bottom right.
+
+## Changes Requiring User Action :id=changes-requiring-user-action

+
+### Bootmagic Full Removal ([#13846](https://github.com/qmk/qmk_firmware/pull/13846)) :id=bootmagic-full-removal
+
+As noted during last breaking changes cycle, QMK has decided to deprecate the full Bootmagic feature and leave Bootmagic Lite as the only remaining option.
+
+This pull request changes the behavior of `BOOTMAGIC_ENABLE` such that specifying `full` results in an error, allowing only `no`, `yes`, or `lite`.
+
+Currently `lite` is the equivalent of `yes` in `rules.mk`. Next cycle the use of the `lite` keyword will be prevented in favour of `yes` -- any new submissions should now be using `yes` or `no` to minimise disruption.
+
+#### Bootmagic Full Deprecation Schedule
+
+This is the current roadmap for the behavior of `BOOTMAGIC_ENABLE`:
+
+- (done) From 2021 May 29, setting `BOOTMAGIC_ENABLE = yes` will enable Bootmagic Lite instead of full Bootmagic.
+- (now) From 2021 Aug 28, `BOOTMAGIC_ENABLE` must be either `yes`, `lite`, or `no` – setting `BOOTMAGIC_ENABLE = full` will cause compilation to fail.
+- (next) From 2021 Nov 27, `BOOTMAGIC_ENABLE` must be either `yes` or `no` – setting `BOOTMAGIC_ENABLE = lite` will cause compilation to fail.
+
+### DIP switch callbacks are now boolean ([#13399](https://github.com/qmk/qmk_firmware/pull/13399)) :id=dip-switch-boolean
+
+To match the encoder change last breaking changes cycle, DIP switch callbacks now return `bool`, too.
+
+Example code before change:
+
+```c
+void dip_switch_update_kb(uint8_t index, bool active) {
+    dip_switch_update_user(index, active);
+}
+
+void dip_switch_update_user(uint8_t index, bool active) {
+    switch (index) {
+        case 0:
+            if(active) { audio_on(); } else { audio_off(); }
+            break;
+    }
+}
+
+void dip_switch_update_mask_kb(uint32_t state) { 
+    dip_switch_update_mask_user(state);
+}
+
+void dip_switch_update_mask_user(uint32_t state) {
+    if (state & (1UL<<0) && state & (1UL<<1)) {
+        layer_on(_ADJUST); // C on esc
+    } else {
+        layer_off(_ADJUST);
+    }
+}
+```
+
+Example code after change:
+
+```c
+bool dip_switch_update_kb(uint8_t index, bool active) {
+    if !(dip_switch_update_user(index, active)) { return false; }
+    return true;
+}
+
+bool dip_switch_update_user(uint8_t index, bool active) {
+    switch (index) {
+        case 0:
+            if(active) { audio_on(); } else { audio_off(); }
+            break;
+    }
+    return true; // Returning true allows keyboard code to execute, false will tell the keyboard code "I've already handled it".
+}
+
+bool dip_switch_update_mask_kb(uint32_t state) {
+    if (!dip_switch_update_mask_user(state)) { return false; }
+    return true;
+}
+
+bool dip_switch_update_mask_user(uint32_t state) {
+    if (state & (1UL<<0) && state & (1UL<<1)) {
+        layer_on(_ADJUST); // C on esc
+    } else {
+        layer_off(_ADJUST);
+    }
+    return true; // Returning true allows keyboard code to execute, false will tell the keyboard code "I've already handled it".
+}
+```
+
+## Notable core changes :id=notable-core
+
+### Split transport improvements :id=split-transport-improvements
+
+Split keyboards gained a significant amount of improvements during this breaking changes cycle, specifically:
+
+* Extensible split data sync ([#11930](https://github.com/qmk/qmk_firmware/pull/11930)) -- rewritten data sharing between sides, allowing for data transfer only when required, as well as enabling keyboards and keymaps to define their own shared data.
+* Full-duplex ARM USART split ([#13081](https://github.com/qmk/qmk_firmware/pull/13081)) -- adds to the previous half-duplex driver and now allows for full-duplex support on ARM.
+* Make solo half of split keyboards (more) usable. ([#13523](https://github.com/qmk/qmk_firmware/pull/13523)) -- allows the slave to be disconnected, enabling one-handed use.
+* Switch split_common to CRC subsystem ([#13418](https://github.com/qmk/qmk_firmware/pull/13418))
+
+!> If you're updating your split keyboard, you will need to flash both sides of the split with the your firmware.
+
+### Teensy 4.x support ([#13056](https://github.com/qmk/qmk_firmware/pull/13056), [#13076](https://github.com/qmk/qmk_firmware/pull/13076), [#13077](https://github.com/qmk/qmk_firmware/pull/13077)) :id=teensy-4-x-support
+
+Updated ChibiOS and ChibiOS-Contrib, which brought in support for Teensy 4.x dev boards, running NXP i.MX1062.
+
+### Data Driven Improvements ([#13366](https://github.com/qmk/qmk_firmware/pull/13366))
+
+QMK's pursuit of data-driven keyboards has progressed, allowing substantially more configurable options to be specified in `info.json`.
+
+#### Tags
+
+Tags will let you categorize your keyboard, and will be used in the future to allow browsing and sorting through keyboards in QMK. Tags are free-form text identifiers that identify attributes about your keyboard. To add tags you simply add a `tags` key to your `info.json`:
+
+    "tags": ["tkl", "backlight", "encoder"]
+
+#### Dot Notation
+
+With this release we are moving towards using JSON dot notation in more places. For example, when using `qmk info -f text`:
+
+```
+$ qmk info -f text -kb clueboard/card
+  bootloader: atmel-dfu
+  debounce: 20
+  diode_direction: ROW2COL
+  features.audio: True
+  features.backlight: True
+  features.bluetooth: False
+  features.bootmagic: False
+  features.command: True
+  features.console: True

+  features.lto: True
+  features.midi: False
+  features.mousekey: True
+  features.nkro: False
+  features.rgblight: True
+  features.unicode: False
+  height: 8
+  keyboard_folder: clueboard/card
+  keyboard_name: Cluecard
+  layout_aliases.LAYOUT: LAYOUT_all
+  layouts: LAYOUT_all

+  manufacturer: Clueboard
+  matrix_pins.cols: F1, F6, F7
+  matrix_pins.rows: B4, F0, F4, F5
+  platform: unknown
+  processor: atmega32u4
+  processor_type: avr
+  protocol: LUFA
+  rgblight.brightness_steps: 17
+  rgblight.hue_steps: 10
+  rgblight.led_count: 4
+  rgblight.pin: E6
+  rgblight.saturation_steps: 17
+  split.transport.protocol: serial
+  usb.device_ver: 0x0001
+  usb.pid: 0x2330
+  usb.vid: 0xC1ED
+  width: 10
+```
+

+# QMK Breaking Changes - 2021 November 27 Changelog
+
+## 2000 keyboards! :id=qmk-2000th-keyboard
+
+QMK had it's 2000th keyboard submitted during this breaking changes cycle.... and it only _just_ made the cut-off!
+
+```shell
+% qmk list-keyboards | wc -l
+2003
+```
+
+From the whole QMK team, a major thankyou to the community for embracing QMK as your preferred keyboard firmware!
+
+## Notable Features :id=notable-features
+
+### Expanded Pointing Device support ([#14343](https://github.com/qmk/qmk_firmware/pull/14343)) :id=expanded-pointing-device
+
+Pointing device support has been reworked and reimplemented to allow for easier integration of new peripherals.
+
+Usages of `POINTING_DEVICE_ENABLE = yes` in `rules.mk` files now need to be accompanied by a corresponding `POINTING_DEVICE_DRIVER = ???` line, specifying which driver to use during the build. Existing keyboards have already been migrated across to the new usage pattern, so most likely no change is required by users.
+
+QMK now has core-supplied support for the following pointing device peripherals:
+
+| `rules.mk` line                                | Supported device                        |
+|------------------------------------------------|-----------------------------------------|
+| `POINTING_DEVICE_DRIVER = analog_joystick`     | Analog joysticks, such as PSP joysticks |
+| `POINTING_DEVICE_DRIVER = adns5050`            | ADNS 5050 sensor                        |
+| `POINTING_DEVICE_DRIVER = adns9800`            | ADNS 9800 laser sensor                  |
+| `POINTING_DEVICE_DRIVER = cirque_pinnacle_i2c` | Cirque touchpad, I2C mode               |

+
+### Dynamic Tapping Term ([#11036](https://github.com/qmk/qmk_firmware/pull/11036)) :id=dynamic-tapping-term
+
+For people who are starting out with tapping keys, or for people who think tapping keys don't "feel right", it's sometimes quite difficult to determine what duration of tapping term to use to make things seem natural.
+
+If you're in this stage of discovery, you can now add `DYNAMIC_TAPPING_TERM_ENABLE = yes` to your `rules.mk`, which enables the use of the following keycodes in your keymap:
+
+| Key       | Description                                                                   |
+|-----------|-------------------------------------------------------------------------------|
+| `DT_PRNT` | "Dynamic Tapping Term Print": Types the current tapping term, in milliseconds |
+| `DT_UP`   | "Dynamic Tapping Term Up": Increases the current tapping term by 5ms          |
+| `DT_DOWN` | "Dynamic Tapping Term Down": Decreases the current tapping term by 5ms        |
+
+Coupled with the use of `qmk console` or QMK Toolbox to show console output from your keyboard, you can tweak the tapping term dynamically in order to narrow down what "feels right" to you. Once you're happy, drop in the resulting number into your keymap's `config.h` and you're good to go!
+
+### Macros in JSON keymaps ([#14374](https://github.com/qmk/qmk_firmware/pull/14374)) :id=macros-in-keymap-json
+
+You can now define up to 32 macros in your `keymap.json` file, as used by [QMK Configurator](newbs_building_firmware_configurator.md), and `qmk compile`. You can define these macros in a list under the `macros` keyword, like this:
+
+```json
+{
+    "keyboard": "handwired/my_macropad",
+    "keymap": "my_keymap",
+    "macros": [
+        [ // first listed is MACRO_0...
+            {"action":"down", "keycodes": ["LSFT"]},
+            "hello world1",
+            {"action": "up","keycodes": ["LSFT"]}
+        ],
+        [ // ...then MACRO_1...
+            {"action":"tap", "keycodes": ["LCTL", "LALT", "DEL"]}
+        ],
+        [ // ...then MACRO_2...
+            "ding!",
+            {"action":"beep"}
+        ],
+        [ // ...and MACRO_3.
+            {"action":"tap", "keycodes": ["F1"]},
+            {"action":"delay", "duration": "1000"},
+            {"action":"tap", "keycodes": ["PGDN"]}
+        ]
+    ],
+    "layout": "LAYOUT_all",
+    "layers": [
+        ["MACRO_0", "MACRO_1", "MACRO_2", "MACRO_3"]
+    ]
+}
+```
+
+In due course, [QMK Configurator](https://config.qmk.fm/) will pick up support for defining these in its UI, but for now the json is the only way to define macros.

+### Squeezing space out of AVR ([#15243](https://github.com/qmk/qmk_firmware/pull/15243)) :id=squeezing-space-from-avr
+
+The AVR platform has been problematic for some time, in the sense that it is severely resource-constrained -- this makes life difficult for anyone attempting to add new functionality such as display panels to their keymap code. The illustrious Drashna has contributed some newer documentation on how to attempt to free up some space on AVR-based keyboards that are in short supply.
+
+Of course, there are much fewer constraints with ARM chips... ;)
+
+### Require explicit enabling of RGB Matrix modes ([#15018](https://github.com/qmk/qmk_firmware/pull/15018)) :id=explicit-rgb-modes
+
+Related to the previous section -- RGB Matrix modes have now been made to be opt-in, rather than opt-out. As these animations are now opt-in, you may find that your keyboard no longer has all the RGB modes you're expecting -- you may need to configure and recompile your firmware and enable your animations of choice... with any luck they'll still fit in the space available.
+
+Most keyboards keep their original functionality, but over time the QMK maintainers have found that removal of animations ends up being the quickest way to free up space... and some keyboards have had animations such as reactive effects disabled by default in order to still fit within the flash space available.
+
+The full list of configurables to turn specific animations back on can be found at on the [RGB Matrix documentation](feature_rgb_matrix.md#rgb-matrix-effects) page.
+
+### OLED task refactoring ([#14864](https://github.com/qmk/qmk_firmware/pull/14864)) :id=oled-task-refactor
+
+OLED display code was traditionally difficult to override in keymaps as they did not follow the standard pattern of `bool *_kb()` deferring to `bool *_user()` functions, allowing signalling to the higher level that processing had already been done.
+
+This changes the standard OLED drawing function model to allow for a base implementation to be provided by a keyboard, but also still allow for keymap-level overrides without needing to modify the keyboard's code.
+
+The old keymap code went something like this:
+
+```c
+void oled_task_user(void) {
+    // keymap drawing code
+}
+```
+
+...but the new keymap code looks like this:
+```c
+bool oled_task_user(void) {
+    // keymap drawing code
+    return false;
+}
+```
+
+Keyboard designers should now structure their keyboard-level drawing routines like the following, in order to allow for keymap overrides:
+
+```c
+bool oled_task_kb(void) {
+    // Defer to the keymap if they want to override
+    if(!oled_task_user()) { return false; }
+
+    // default keyboard drawing code
+    return false;
+}
+```
+
+### Bootmagic Full Removal ([#15002](https://github.com/qmk/qmk_firmware/pull/15002)) :id=bootmagic-full-removal
+
+As noted during previous breaking changes cycles, QMK decided to deprecate the full Bootmagic feature and leave Bootmagic Lite as the only remaining option.
+
+This removal is now complete!
+
+This pull request changes the behavior of `BOOTMAGIC_ENABLE` such that specifying `lite` or `full` results in an error, allowing only `yes` or `no`, with `yes` mirroring historical `lite` functionality.
+
+All use of the `lite` keyword within the repository has been migrated to `yes` -- any new submissions using `lite` will now fail to build and should be updated accordingly.
+
+#### Bootmagic Full Deprecation Schedule: Complete!
+
+This is the historical timeline for the behavior of `BOOTMAGIC_ENABLE`:
+
+- (done) From 2021 May 29, setting `BOOTMAGIC_ENABLE = yes` will enable Bootmagic Lite instead of full Bootmagic.
+- (done) From 2021 Aug 28, `BOOTMAGIC_ENABLE` must be either `yes`, `lite`, or `no` – setting `BOOTMAGIC_ENABLE = full` will cause compilation to fail.
+- (now) From 2021 Nov 27, `BOOTMAGIC_ENABLE` must be either `yes` or `no` – setting `BOOTMAGIC_ENABLE = lite` will cause compilation to fail.
+
+### Remove QWIIC_DRIVERS ([#14174](https://github.com/qmk/qmk_firmware/pull/14174)) :id=remove-qwiic
+
+Due to minimal QWIIC adoption and other options for similar functionality, the QWIIC drivers were removed from QMK. Existing OLED usages have been migrated across to the normal QMK OLED driver instead.
+
+## Notable core changes :id=notable-core
+
+### New MCU Support :id=new-mcu-support
+
+QMK firmware picked up support for a handful of new MCU families, potentially making it a bit easier to source components.
+
+QMK firmware is now no longer limited to AVR and ARM - it also picked up support for our first RISC-V chip, the GD32VF103.
+
+* Add support for RISC-V builds and GD32VF103 MCU ([#12508](https://github.com/qmk/qmk_firmware/pull/12508))
+* Add HT32 support to core ([#14388](https://github.com/qmk/qmk_firmware/pull/14388))
+* Westberrytech pr ([#14422](https://github.com/qmk/qmk_firmware/pull/14422))
+* Initial pass of F405 support ([#14584](https://github.com/qmk/qmk_firmware/pull/14584))
+
+### EEPROM Changes :id=eeprom-changes
+
+There were a few EEPROM-related changes that landed during this breaking changes cycle, most prominently the long-awaited ability for the Drop boards to gain persistent storage. Any users of the Drop CTRL or Drop ALT should update QMK Toolbox as well -- coupled with a QMK firmware update settings should now be saved.
+
+* massdrop alt/ctrl: support saving into nvm ([#6068](https://github.com/qmk/qmk_firmware/pull/6068))
+* Implement F4 eeprom ([#14195](https://github.com/qmk/qmk_firmware/pull/14195))
+* make the full 4096 bytes of EEPROM work on Teensy 3.6 ([#12947](https://github.com/qmk/qmk_firmware/pull/12947))
+* Further tidy up of STM32 eeprom emulation ([#14591](https://github.com/qmk/qmk_firmware/pull/14591))
+* Enable eeprom with F401xE ld ([#14752](https://github.com/qmk/qmk_firmware/pull/14752))
+
+### Compilation Database :id=compile-commands
+
+A clang-compatible compilation database generator has been added as an option in order to help development environments such as Visual Studio Code.
+
+Running `qmk generate-compilation-database -kb <yourkb> -km <yourkeymap>` from within the QMK firmware directory will generate a `compile_commands.json` file -- using a compatible IDE will likely see this and correctly start detecting the correct locations for source files as well as type and function information that are relevant to your build.
+
+Do note that switching keyboards will require re-generation of this file.
+
+* New CLI subcommand to create clang-compatible compilation database (`compile_commands.json`) ([#14370](https://github.com/qmk/qmk_firmware/pull/14370))
+* compiledb: query include paths from gcc directly. ([#14462](https://github.com/qmk/qmk_firmware/pull/14462))
+
